Question: Selector node about behavior3js

[renatopp]

Hey @EskelCz, Selector is sometimes referred as Priority, the name we use here. I always get confused when people use selector and sequence - priority avoid this kind of confusion.

I'm closing this issue, feel free to comment or reopen it if necessary.

Hi @renatopp, thanks for the answer.

I got the impression that Sequence is meant to call all nodes in you know, a sequence... but Selector to select just one. Hence the Selector. :)

I imagined a selector 'isEnemyNear' which would activate either actions 'idle' or 'run' based on some distance measuring logic. The simplest example imaginable.

From what I read in the documentation, the priority node seems to require the logic to be in the children, as to return SUCCESS or FAILURE to decide the tick propagation. Because I imagined the 'run' would always return success. Should there be another layer of nodes with the distance checking logic, before actions?

Or is it that ticking does not equal running the action? I'm confused :)

The simple example would help tremendously. Preferably with a node graph exported from the editor and the logic attached in code. That's a puzzler as well. :)

Thank you very much for clearing this out.

I've read some more about the topic, I see how I was wrong.
I recommend explanations and examples from this library:
